PATENT OFFICE LAMP SHADE William J. Keller, St. Louis, Mo.

Application August 6, 1937, Serial No. 157,659

3 Claims.

This invention relates, generally, to lamp shades and more particularlyto the type of lamp shade that is supported directly by the glasschimney of a lamp.

The primary object of the present invention is to support the shadeconcentric with the chimney in such a manner as to prevent tiltingthereof relative to the chimney.

A further object of the invention isto provide a wire spider structurefor the shade having a ring contact therewith and a plurality of pointcontacts therewith above the ring contact.

Other objects of the invention are to provide an article of the classmentioned which will be comparatively simple and inexpensive in. thecost of manufacture, wherein the shade is readily appliedto a lampchimney and removed therefrom, Q

and, when supported by the lamp chimney, is held against tiltingdisplacementrelative thereto.

All of the above and still further objects and advantages of the presentinvention will become apparent from a study of the followingspecification read in connection with the accompanying drawing, whereinlike characters of reference denote corresponding parts throughout theseveral views, wherein:-

Fig. l is a. view partly in sectional side elevation and partly insectional elevation of a lamp shade embodying the features of myinvention, and shown as supported by the chimney;

Fig. 2 is a top plan View of the invention with parts thereof brokenaway, and shown as sup- I tively small wire ring 5 which ring isslightly lar-gported by a glass lamp chimney.

Referring to the drawing, the reference character A designates a lampburner, preferably oil lamp burner, and, the reference character Bdesignates, generally, a glass lamp chimney having a bulged tubularlower portion l and a straight upper tubular portion 2.,

The reference character C designates, generally, the lamp shade which isadapted tobe supported by the chimney B as hereinafter described.

The shade designated, generally, as 0, comprises an upper wire ring 3, alower wire ring 4 preferably of larger diameter than the upper ring 3,the shade material 4 connecting the two rings 3 and 4, and a wire framestructure designated, generally, as D, which is suspended from the upperring 3.

In carrying out the present invention, I em-v ploy, in combination withthe upper ring 3, a relaer in diameter than the outside diameter of theupper straight tubular portion l of the chimney B, and, which is adaptedto rest on the upper end of the bulged portion 2 of the chimney adjacentthe lower end of chimney portion I, as will be more clearly apparenthereinafter.

As clearly shown in the figures of the drawing,- the wire framestructure includes the upper ring 3 and the chimney engaging ring 5 andthe rings are connected by means of a plurality of wire arms, which willnow be described.

Each arm, of which there are four shown, but which may be of any desirednumber, such as 10 three or more, includes an inwardly and downwardly orhorizontally inclined wire arm portion 6 which terminates in anarcuately bent corner 1 and which, in turn, projects downwardly andslightly outwardto provide vertically inclined 15 wire arm portions 8.The outer end of each arm portion 6 is suitably secured to the wire ring3, such as by soldering, or welding, and, the lower end of each armportion 8 is suitably secured to the ring 5, such, for instance as bysoldering, or welding.

It will be apparent that the upper ring 3, the lower ring 5 and theirconnecting arms form the wire frame or spider structure, and that thering 5 of said structure encircles the chimney B and 25 is supportedthereby, as hereinbefore described.

The corners 'l of said arms substantially engage, or contact the upperportion I of the lamp chimney B for holding or bracing the lampshadeproper concentric with the chimney, and, toprevent any possible tiltingdisplacement of the shade relative to the chimney, due to the fact thatthe arm corners l serve to point contact the chimney a suitable distanceabove the chimney engaging ring 5. 35

The arms of the frame, or spider structure D serve as brace arms, and inuse, the corner portions 1 thereof will spread or expand outwardly withthe chimney, when the chimney becomes hot, due to the angularconstruction of the wire arms, 40

and, they will contract or move toward the longitudinal axis of thechimney when the chimney be comes cold. The vertically inclined armportions 8 of the spider structure form a sort of skeleton sleeve forthe chimney to pass through, with the 5.

tion upon the chimney, and, it is readily and quickly mounted upon thechimney and removed therefrom and will not have a tendency to crack thechimney, due to the fact that the ring 5 will automatically raise itselfupon the chimney when 55 the chimney becomes hot and expands as it isslightly larger in diameter than the straight tubular portion I thereof,and, because of the fact that the corners I of the arm portions 6 andarms 8 flex outwardly with expansion of the chimney portion I when thechimney becomes hot, and return to normal position as the chimney coolsoil.

The many advantages of the herein described invention will readilysuggest themselves to those skilled in the art to which it appertains.

While I have herein described the preferred embodiment of the invention,it is, of course, understood that minor changes in the construction,arrangement and combination of parts may be made, wherein they do notinvolve the exercise of invention and fairly fall Within the scope ofthe appended claims.

What I claim is:

1. In a lamp shade, in combination, a pair of wire rings having shadematerial connecting the rings, a spider including a plurality of armsand a ring adapted to'be seated upon and around a lamp chimney, and saidarms being bent intermediate their ends to form knees adapted to contactthe chimney at pointsabove the ring to hold the shade concentric withthe chimney.

2. In a lamp shade, in combination, a pair of wire rings having shadematerial connecting the same, a spider including a plurality of arms anda chimney ring, the arms being connected at their inner ends to thechimney ring and at their outer ends to one of the said pair of rings,the chimney ring adapted to be seated upon and around a lamp chimney,and said arms being bent intermediate their ends to form knees adaptedto contact the chimney at points above thechimney ring and to providerelatively short arm portions disposed out of parallel relation with theaxis of the chimney between the knees and the chimney ring.

3. A spider for lamp shades including a chimmy ring and a plurality ofspider arms, the spider arms being bent intermediate their ends toprovide inclined long portions adapted to be secured to an upper shadering and the short portions secured to the outside of the chimney ring,and, by being bent, providing knees for contact with a chimney at pointsabove the chimney ring, which ring is adapted to be seated upon and.around the chimney and with the short portions of the spider arms out ofcontact with the chimney between the knees and the chimney ring.
